Introduction of 3D shapes/Solid Shapes for primary 6 Students Hope it will be help the students to learn about the 3D shapes

1. Welcome
To The Fascinating World
Of
3D Shapes

2. Cube Sphere
Cuboid
Triangular based
pyramid
Triangular
prism

3. Our Topic Of Discussion
• Cube.
• Cylinder.
• Sphere.
• Prism.
• Pyramid.

4. 3D Shapes
• 3D shapes can be solid or hollow.
• 3D Shapes has 3 dimension:
– Length.
– Width.
– Height.

5. Now Some Technical Terms
To Address
3D Shapes
• Surface.
• Face.
• Base.
• Edge.
• Corner
• Vertex (singular)/Vertices (plural)

6. Surface
• The curved part of a 3D shape.
• Eg: Cylinder & Cone
Surface

7. Face
• Part of a 3D shape that
is flat.

8. Base
• The bottom
face of a 3D
object.
Base

9. Edge
• The line where two faces meet on a 3D object.
6 Edges
5 Edges

10. Corner
• The point where three
or more edges touch.
• This cube has 12
corners all together.

11. Vertex (Vertices)
• The point where three or more edges meet.
• This cube has 12 vertices all together.

12. Cube
• A three-dimensional shape which has:
–6 Faces (All are of the same size)
–12Edges
–8Corners/Vertex
edge
vertex
face

13. Cylinder
• A three-dimensional shape which has:
–2 Faces
–1Surface
–0Edges
–0Corners/Vertex
face

Surface

14. Sphere
• A three-dimensional shape which has:
–0 Faces
–1Surface
–0Edges
–0Corner /Vertex
Surface

15. • There are different types of prisms and they
are based on the shape of its bases:
–Rectangular Prisms
–Square Prisms
–Triangular Prisms
–Hexagonal Prisms
Prism

16. Pyramids
• There are different types of pyramid and they
are based on the shape of its bases:
• Have 1 base.
• Have Triangular side faces that meet at one
Vertex.
• Examples: Square Pyramid, Triangular Pyramid, Rectangular pyramid etc.
base
Triangular face

17. Square Pyramid
• A three-dimensional shape which has:
–5 Faces (1 square and 4 triangles)
–8Edges
–5Corner /Vertex

18. Rectangular Pyramid
A three-dimensional shape which has:
–5 Faces (1 Rectangular + 4 Triangles)
–8Edges
–5Corner /Vertex
Rectangular face
Triangular face

19. Prism Vs Pyramid
PRISM
-At least 3 Faces that are
Rectangles.
-Two congruent faces on
top and bottom called
bases.
-The shape of the base
determines what type of
prism the figure is.
PYRAMID
-At least 3 Faces that are
Triangles.
-One base.
-The shape of the base
determines what type of
prism the figure is.
